Absorption recovery: Activated carbon can adsorb many organic solvents. In the solvent recovery process, when the exhaust gas or waste liquid containing solvents passes through the activated carbon bed, its solvent molecules will be adsorbed by the porous structure of activated carbon and stay on the surface of activated carbon, thus removing the solvents from the gas or liquid and making solvent recovery and reuse possible.
Desorption and reuse: The solvent adsorbed onto the activated carbon can be desorbed from the activated carbon by raising the temperature, lowering the pressure, or changing the environmental conditions so that the solvent can be reused. The desorbed solvent can be separated and recovered by condensation, condensation, and distillation to obtain a high purity solvent.
Activated carbon recycling: The desorbed activated carbon can be used again to adsorb new solvents, thus realizing the recycling of activated carbon and reducing the cost and environmental impact of the solvent recovery process.
At present, activated carbon in the market is prone to difficulties such as fast adsorption saturation rate, short usage time, and low regeneration rate in solvent recovery applications, which not only brings great trouble to customers but also is a major problem for activated carbon manufacturers.
Recently, Huamei Activated Carbon has developed a new type of activated carbon specifically for solvent recovery. In the application field of activated carbon, the pore size ratio of activated carbon (macropore, mesopore, and micropore) plays an important role. In the field of solvent recovery, the ratio of mesopores of activated carbon plays an important role. The larger the volume of mesopores, the faster the rate of absorption and removal. We have developed this activated carbon through a special process, which increases the volume of mesopores and greatly improves the effect of solvent recovery.
